IMPROVEMENT IN ItIlI:`I.|IlCTOItSl FOR WINDOWS.

T0 ALL PERSONS TO WHOM THESE PRESENTS SI-IAIL COME:

Be it known that I, CHARLES G. SMITH, of North Bridgewater, inthe county of Plymouth, and State of Massachusetts, have invented a new and useful or improved Reecting Apparatus for Windows; and I do hereby declare the same to be fully described in the following specification and represented in theaccompanying drawings, of which- Figure 1 is a rear elevation.

Figure 2, a side elevation, and y Figure 3 a longitudinal section of it.

Figure 4 is a horizontal section taken through its mirrors.`

In the drawings, A represents a box, whose form, top view, is that of a truncated sector of a circle. The opposite sides of the box are arranged to radiate from a common centre, and each'has a mirror, B, applied and ixed to it. The said mirror may be a plane, convex, or concave one, as may be desirable. The box is mounted upon an arm, C, and so as to be capable of being turned on a centre-pin or screw, a, projecting upward from the arm near its inner end. A clamp-screw, b, applied to the arm, and going through a curved slot, c, made in or through the bottom of the box, and being screwed into a nut, n., arranged within the box, serves to clamp the box to the arm. 'The box may be turned horizontally on the arno, and may be xedin position thereon by means of the clamp-screw. Near its inner end the arm is bent at aright angle, and is secured to an upright bar, D, by means of a clamp-screw, d, which goes through the part e ofthe arm, and is screwed into the bar D. By means of the above-described mode of connecting the arm and bar the box may beturned in a vertical plane so as to adjust its mirrors to any desirable inclination with the horizon. The bar D has av long slot, f, made in it lengthwise, and is placed against another bar or standard, E, with whichit is kept in contact by two clasps, g g. A clamp-screw, h, goes through the slotf, screws into the standard E, andserves to confine the bar D to the said standard. From the above it will be seen that the part D may be adjusted to any desirable altitude within the range of its motion on the standard, the same-being so as t'o enable the mirrors to be arranged ata convenient height for a person to see into either while sitting or standing at a window to which the apparatus may be applied. The lower part of the standard is formed with a tenori, t', to enter a mortise, k, I xmde in the head Zof a screw, F, which is to be screwed horizontally into the window-sill.

I am aware that it is not new to have a recctor applied to one side of a window-frame, and provided with adjusting devices, whereby such mirror may be adjusted so as to reflect to an observer within the apartment to which the window may belong the images of objects in the street or country outside ofthe apartment. I therefore make no claim to such in the abstract My appara-tus is designed to be fixed to themiddle of a window-sill, and in such manner that its support-screw will not be an obstacle to the operation of the outside blinds or shutters of`the windows. The advantage of my apparatus is that it exhibits redections in opposite directions, that is, up street as well as ldown street, and can be used by' a person at either side of the window. I

I therefore claim as my inventionj 'The duplex adjustable reector, substantially as described, -that is, as composed of the box A orits equivalent, the two mirrors B B, the arm C, and its clamp-screw 6.

I also claim the combination of the duplex reiiector, made as described, (viz, of the box A, its mirrors B B, larm C, and clamp-screw 6,) with the supporter, composed of the screw F and a bar orbars lD E, applied together and to the arm C substantially as specified. i
